That was my first thought, but I thought since it's being used, it
should be done as well as possible. The previous test was for GCC 3.3,
which must have been wrong for even more environments, since the
relevant parts of GCC haven't changed between 3.3 -> 3.4 AFAIK.

That's certainly the case on FreeBSD 4. But because that file #includes
<wchar.h> rather than <cwchar> wcscmp() _is_ available, so I tried to
make it work. Probably shouldn't have tried. Sorry.
